Blocking message queue mechanism

Hello

We are in the configuration MP with masters on AIX and slaves on HP or Windows.

On the slaves, in the ulog, sometimes we have the error message "CMDTUX_CAT:1380: ERROR: the Message Queue blocking warned childbirth, Qaddr = xxxxxx".

She seems to happens because the BRIDGE process received a message from the network and could not place the message in the queue expected CPI (serverbacked to the top or parameters of resource system IPC too weak or too overload the machine...).

What happens in this case?

the request message is ignored by Smoking and Tuxedo sends an error message to the sender of the request?

or Tuxedo place the message on another queue of the CPI of the same type?

Thanks in advance

TIBUS

Hi Max,.

The message is discarded and the sender may or may not get an error message which is the sender.  If it is a request then the request timeout message and the caller you will get an error.  However if there is a response message then the message will simply be abandoned because there is no way to tell the server that sent the response that the message has not been delivered.  Usually, this is caused by the IPC resources being set too low, even if it could be because a server is severely backed up.

  • CMDTUX_CAT:1380: ERROR: the Message Queue blocking warned childbirth

    Today, I changed a Tuxedo (server) application for product systems (a master and two slaves). Only a small change in the code. But after a period of running, there are a lot of mistakes in ULOG:

    CMDTUX_CAT:1380: ERROR: the Message Queue blocking warned childbirth, Qaddr = 583902

    And then the server died. After restarting the server, this will happen again later.

    I don't know why this happens? THX.

    Hi Bill,

    This happens because the BRIDGE process received a message from the network and could not place the message in the expected IPC queue. This could be because the server handles this message is saved, or the parameters of the system IPC resources are too weak. Please check the recommended actions:

  • Now that the status bar is gone, how can I turn back on the "pop-up blocked" message once I have it disabled? (Firefox 21,0)

    I activated the function 'block pop-up windows' in the menu Options/content of Firefox 21.0. When a message appeared telling me that the pop-up window a site had been blocked, I have chosen to "do not display this message" again.

    Now, I want to turn on the "pop-up blocked" message. I don't know its place in the menu of Options or elsewhere to do. In previous versions of Firefox, there was once an icon in the status bar where I could re-enable the message of 'pop' - up blocked. Now that the status bar is gone, where I'm going to to reactivate?

    When I test with disabled messages *, I have an icon in the URL bar (screen attached). What do you get?

    * privacy.popups.showBrowserMessage

  • How can I activate the pop-up blocked message?

    How can I activate the pop-up blocked message? When the message came I clicked on do not show this message again. I want this message to show when Firefox blocks a menu embedded, so I can allow the pop up if I want to.

    You can see a pop-up block icon in the right corner of the status bar if you have chosen to hide the information bar at the top.

    You can click on this icon of pop - up block on the status bar and remove the check mark [] «do not show an information message when pop-ups are blocked»

  • Tuxedo of Oracle and Oracle Tuxedo message queue on a virtual machine.

    Hi friends.

    How is it going?

    A small question.

    So let's go live using Oracle Tuxedo 12.1.1.0 with binding distinguished Bulletin Board and Oracle Tuxedo Message Queue 12.1.1.0 on a Virtual Machine (VMWARE) running Oracle Linux 6.2. However, we want to know if there are recommendations or mishaps in which we face before running Oracle Tuxedo on a virtual machine?

    I mean, I wonder if I have to worry about kernel parameters, settings of virtual machine or any other thing that could ruin everything.

    Another question.

    Oracle also provides certification of VMS where Tuxedo Oracle would go on top of the?

    Hi Bruno.

    I'm not sure what you mean with single Liaison Bulletin Board.  I guess you mean a cluster or the MP configuration?  And is it really a clustered or just a single machine of the MP configuration?

    About the configuration, you use Tuxedo services as well or just Tuxedo Message Queue?  The biggest problem with the configuration of the BONE is the IPC resources.  If you do a-c tmloadcf on your UBBCONFIG file, it will help you to determine the required minimum IPC resources.  In general, I suggest configuration much more resources than the minimum to allow for the changes to come and for some of the parameters for heavier loads.  In particular IPC message queue settings are strongly dependent on the load.  So make sure that the maximum message size and the size of the queue are big enough for your expected workload.  You can monitor the slot load using the ipcs command.

    We don't certify virtual machine environment, but support also a long time the VM vendor to ensure compatibility, obviously VMware and Oracle VM who both do.

  • WebLogic 12.1.2 MDB TransactionManagementType.BEAN blocking messages

    Hello

    When we have a managed Bean MessageDriveBean we see that some messages are blocked.

    Setup is a simple queue where we set a deadline for re-delivery of 5 times, and spread to a queue of the error later.

    We also have a single execution thread for the MDB:

    < max-son-constraint >
    < name > xxx_mdb_maxtrheads < / name >
    < number > 1 < / count >
    < / max-son-constraint >

    In the test case send us 10 correct messages to the queue of waiting, then 2 false messages (inconsistent messages) and then again 20 correct messages.

    When the MDB is a poison message just throw us an exception.

    This is the journal that we see:

    TextMessage [ID: < 130550.1393589299935.0 >, 9]
    TextMessage [ID: < 130550.1393589299937.0 >, Poison message 1]
    TextMessage [ID: < 130550.1393589299961.0 >, 18]
    TextMessage [ID: < 130550.1393589299963.0 >, 19]

    TextMessage [ID: < 130550.1393589299956.0 >, 16]


    The strange thing is that we do not see the manipulation of re-deliveries "Poison message 2" until all configured to the "Poison 1" message have been treated.

    We only see this error when the MDB is defined as managed Bean.

    Testing the same code simply by changing the MDB in the managed container is to give the newspaper waited:

  • Obsolete blocking message - Flash Player Plugin between 11.0 and 11.7.700.169 (click-to-play) has been blocked for your protection.

    I can't play Flash videos on any Web site using Firefox 35.0.1

    The latest version of Shockwave Flash is 16.0.0.296 from 2015-02-12.

    The deadlock message is obsolete, because it refers to a set of versions of Flash much earlier.
    All versions of Flash has a vulnerability, or are there some that are actually clean (for more than a few seconds)?

    Can someone fix the deadlock message to reflect the real reason for blocking?

    Where can I find a version that is not vulnerable, or is it a utopia?

    Because 16.0.0. 296 is not aware, because it is vulnerable to exploits criticism proved in nature. The 16.0.0 Flash Player. 305 and 13.0.0. 269 ESR are the current versions of Windows/Mac OSX since Feb 4/5.

    https://www.Adobe.com/products/flashplayer/distribution3.html

    https://helpx.Adobe.com/security/products/Flash-Player/apsb15-04.html
    https://addons.Mozilla.org/en-us/Firefox/blocked/

    More updates Adobe Flash Player are for reasons of security and stability fixes. However before December 9, Mozilla is not added all versions of Flash to the red list since the beginning of 2013. The reason now is because critical exploits that is in older versions (not with corrections) and Adobe tried to fix with five updates for 16.0 Flash itself since 9 dec. Mozilla only adds Extensions and Plugins versions to list when it is security, stability or malware.

    As to why some receive the old Flash 11 blocklisting I can't say.

  • I get a "MALICIOUS URL BLOCKED" message when you connect to gmail or iGoogle home page, ONLY WITH FIREFOX (not with Internet Explorer). Help!

    For the past two weeks, whenever I connect to gmail or iGoogle home page I get a message from avast! Antivirus (free version) saying that it has detected a malicious site. This only happens when using Firefox. No message is displayed if I connect using Internet Explorer 8. I use Windows XP Pro Service Pack 3, avast! Version 6.0.1367 (updated daily), Mozilla Firefox 10.0. I also use Malware Anti-Malware and SUPER Anti Spyware, bytes that are also updated regularly. The only recent downloads in my system were version 10.0 of Firefox and Microsoft Updates. I even tried to roll back to version 9, no change or improvement. This is the URL that is blocked, as shown in the pop-up message: OBJECT: http://74.50.117.107/js/je.php?u=739ec4a2-4903-4c0d-aee6-bdb3d2cdb87c & a = 200 & i = 111 & s = 0 INFECTION: PROCESS URL: MAL: C:\Program Files\Mozilla Firefox\firefox.exe. What worries me, because it barely resembles the horizon, and I do not use IE, it is slower and does not include Ad Block, which I use a lot (apart from the fact that Microsoft is trying to push me to buy Windows 7 * IE9 does not work with XP *, which would require the upgrade my computer and for the moment there is no budget available.). I thank in advance for the help, you can send my way.

  • Synchronization in the messaging queue manager

    Hi all

    I have a program of Messaging Manager similar to the model for measuring continuously and logging (CML) queued.  Events on the front panel creating a message from queue UI"who receives the interface user Messenger Handler.  The Messenger user interface handler then sends a message to queue data"to my vi data loop.  (It is similar to the acquisition loop in the model of the CMA).

    The loop of data vi is intended to read messages sent priority from the interface user Messenger Handler, such as start, stop, terminate. When he reads the startup message, he enters with the case of boot and continually performs a task once every milliseconds X.  When sending a priority stop message, it should immediately cease to perform the tasks.

    I think it should involve the data loop continuously sending messages to perform the task.  In this way the priority message could easily slide forward and stops the process.  Is that a correct implementation?  If so, how can ensure me that the task is done at the right time?

    Thank you!

    Just to restate what Bob says...

    The time-out period is as your source of synchronization.  So, if no message has been received within the given time (negative expectations are infinite wait), then the queue returns the default value for the type of data (e.g. empty string to a string data type) and the release of "Timedout?" is set to TRUE.  You can detect this and perform any action you want your intervaled rate.

    The beauty of this Setup is that if something happened to you can handle immediately.

  • How to block messages from 3 KB or under?

    I continue to receive waste / * links with words at random in the message if cannot filter by select Word. Messages are always of 3 KB or slot so if I could block all messages of 3 KB and under that would be great. I see there is a rule for 3kb and above, but not under. Regards Tony

    You can set up a message rule that when a message is larger than a certain size (e.g., 3kb) and "stop processing more rules".  Then set up a later rule that, "for all messages', move them to a junk folder (created by the user).  Then any message under 3 k will go to a junk e-mail folder, where you can filter.

    You can configure a similar rule above it where the messages are for you, then stop processing more rules.  You will not specifically then all get dumped into the junk e-mail folder.
